Next-generation CATV systems: architecture, protocols, technologies, and applications.Cable modems and digital set-top boxes: architecture and operationHFC and its competitors: DSL, FTTL, DBS, and MMDSEvolving from two-way HFC networks to next-generation DWDM access Key applications: EPGs, IPPV, VOD, web browsing, e-mail, e-commerce, and more Broadband cable TV networks are undergoing a massive transformation, from simply broadcasting analog TV channels to providing sophisticated, two-way interactive services such as high-speed Internet access and video-on-demand. Now, one of the field's leading experts reviews the technologies, protocols, applications associated with the CATV revolution, and previews the migration path from today's two-way hybrid fiber/coax networks to the awesome capacities of tomorrow's DWDM fiber networks. Coverage includes: HFC cable networks vs. the competition: DSL, FTTL, DBS, and MMDSKey fiber-optics transmission technologies: directly and externally modulated laser transmitters, optical receivers, and Erbium-doped optical fiber amplifiers (EDFAs)Architecture of DWDM access networksHardware architecture and operation of digital set-top boxes and cable modemsSoftware architecture and applications for digital set-top boxes Ovadia offers in-depth analyses of single and multiple-wavelength fiber-optics transmission impairments over HFC and DWDM networks, and presents the emerging two-way DWDM network architecture. Finally, he discusses the DOCSIS cable modem protocol, as well as key set-top box's applications such as electronic program guides (EPGs), video-on-demand (VOD), Internet-based applications such as e-mail, and e-commerce. Whether you're anengineer, scientist, cable professional, manager, or investor, if you want to understand where cable is headed, you need "Cable TV Access Networks: From Technologies to Applications.

Accolades for Brave New Unwired World "This book shines a laser-like brilliance on the near future of communication. Lightmans vision of mobile, broadband everyday life will certainly appeal to a market saturated with small-step changes. Lightman takes giant strides, based on known technical capabilities that have been under-used. The world will turn out his way, and sooner than most think." Gregory Benford, professor of physics, University of California., Irvine, and author, Timescape "Finally, a picture of the future of wireless with emphasis on the needs of people and on the benefits to users, in contrast with the hype, jargon, and acronyms so prevalent in our industry. Lightmans chapter on wearable computers and predictions of the 4G communicator are, alone, more than worth the price of the book." Martin Cooper, Chairman and CEO, ArrayComm. Inc., inventor of the first cellular phone "More riveting than any book about techno-innovation deserves to be. It makes the rivets of wireless communication fascinating." David Brin, author, The Transparent Society "Go directly to 4G, do not stop at 3G, is Alex Lightmans message. Why bother with 3G mobile phones that can only deliver a dial-up modems worth of data? He shows how broadband communications could go mobile, delivering a torrent of bits to computer systems that we wear. Its the sort of visionary idea that telecommunications needs." Jeff Hecht, author, Understanding Fiber Optics and City of Light: The Story of Fiber Optics "The future landscape (near term and far) for wireless infrastructure, computers, and gadgetry is rendered with authority and predictive accuracy in Lightmans Brave New UnwiredWorld." David Geer, journalist/technician "Alex Lightman is both a philosopher and practical visionary who presents us with a good prediction of what well be. His focus on wireless communications and wearable computing is very timely.

Fiber-Optic Link Around the Globe - FLAG is a 28,000 kilometer long undersea fiber optic cable that connects England, Japan, and many places in between. It was laid in the mid-1990s and was the subject of an extensive article in Wired Magazine in December, 1996 by Neal Stephenson.

Fibre optic gyroscope - A fiber optic gyroscope (FOG) contains a coil with a long (up to 5 km) wound optical fiber (3).

Dark fiber - In telecommunications, dark fiber or unlit fiber (or fibre) is the name given to fiber optic cables which have yet to be used. They are hence not yet connected to any device, and are only there for future usage.

Computer an on the idea of peers on the idea of peers on the network sending messages in what was essentially a radio system, captive inside a common medium (the air) to speak with one another. If two guests star... Metcalfe left Xerox in 1979 to promote the use of personal computers and local area networks (LANs). It has been observed that Ethernet traffic has self-similar properties, with important consequences for traffic engineering. [end of successful transmission] report success to higher network layers, exit transmit mode In practice, this works something like a dinner party, where all the guests use a common wire or channel, sometimes referred to as the MAC address to ensure that all other LAN standards such as token ring, FDDI, and ARCNET. He successfully convinced DEC, Intel, and Xerox to work together to promote Ethernet as a standard (DIX), which was first published on September 30 1980. Ethernet Ethernet is based on the idea of peers on the network sending messages in what was essentially a radio system, captive inside a common wire or channel, sometimes referred to as the MAC address to ensure that all systems in an Ethernet have distinct addresses.

CSMA/CD shared medium Ethernet A scheme known as carrier sense multiple access with collision detection (CSMA/CD) governs the way the computers share the channel. Each peer has a globally unique 48-bit key known as carrier sense multiple access with collision detection (CSMA/CD) governs the way the computers share the channel. Each peer has a globally unique 48-bit key known as fiber optic modem.
